The objective of this work was to study the adsorption and separation of the most important families of hydrocarbon compounds on metal-organic frameworks (MOFs), in comparison with zeolites. For this purpose, we have selected four probe molecules, each of them representing one of these families, i.e., o- and p-xylene as aromatics, 1-octene as an alkene, and n-octane as an alkane. The separation...

Selected results for the synthesis of cyclic olefin copolymers (COCs)—especially copolymerizations of norbornene (NBE) or tetracyclododecene (TCD) with ethylene and α-olefins (1-hexene, 1-octene, 1-dodecene)—using group 4 transition metal (titanium and zirconium) complex catalysts have been reviewed. Half-titanocenes containing an anionic ancillary donor ligand, Cp’TiX2(Y) (Cp’ = cyclopentadien...

Abstract To overcome the severe toxicity and blind absorption zone of conventional lead-based shielding materials for X-rays in 70–90 keV range, lead-free multilayered polymer composites were designed fabricated. The effects direction incidence number layers as well layer thickness ratio (tungsten/ethylene-octene copolymer)/(bismuth/ethylene-octene copolymer) layered on their efficiency studied...

Abstract To utilize Cu-benzene-1,3,5-tricarboxylate (Cu-BTC) adsorbed lubricant oils in the self-lubricating field, adsorption properties of Cu-BTC on different 1-olefins must be clarified. In this work, 1-hexene, 1-octene, 1-nonene, 1-decene, 1-undecene, and 1-dodecene were studied by Monte Carlo method experimentally. The limit for n-olefins was determined as 1-undecene isotherms. This sugges...

This work describes the synthesis of ultra-small non-crystalline and non-metallic iron-based nanoparticles in solution from easily accessible commercial products mild conditions. These colloidal suspensions were further used to generate well-defined solids containing metallic iron or oxide NPs. While classical magnetic crystalline Fe are inactive alkene hydrosilylation, such original NPs active...

The Suzuki-coupling reaction of 2-(dihydroxyboryl)-3,4-dimethyl-2-cyclopenten-1-one and 2-(dihydroxyboryl)-3-methyl-2-cyclopenten-1-one with 2-bromoaniline derivatives affords cyclopentenone compounds from which cyclopentadiene compounds, 4,6-R'(2)-2-(2,5-Me2C5H3)C6H2NH2 and 4,6-R'(2)-2-(2,3,5-Me3C5H2)C6H2NH2 are prepared. After sulfonation of the -NH2 group with p-TsCl, metallation is carried ...
